BK-14, OAL 7", edge 3.25"
The good:
* 29.99 cost - probably the best value for a fixed blade out there
* Comes with a decent sheath that is configurable for a variety of uses with a bit of 550 cord
* Black powder coat is very durable
* Easy to sharpen, 1095 carbon steel
* Excellent ergonomics (a combination of the "Becker Necker" blade profile and the RAT Izula handle)
* A variety of inexpensive options for the scales, such as naked (my preference), cord-wrapped, and $15 micarta scales for the Izula which can be modified to fit in about 10 minutes with an exacto knife
The bad:
* No jimping whatsoever. If you grind jimping in yourself with a file or dremel, you have to cut into the black powdercoat
* The sheaths shipped with early models were actually for a tanto blade profile, resulting in some sheath rattling (problem has been corrected since)
* On my 3 examples, the factory edge was unacceptably dull. There is no good excuse for this; it's like selling a sports car with tires at 20 psi. Not hard to correct, but a nuisance and it drastically affects performance
* A notch between the guard and the sharpened part of the blade makes the blade stick in fabric on draw cuts, requiring modification if you want a good self-defense knife
It's a nitpicky list of complaints, to be sure. You can sharpen a knife like this very easily with a variety of systems; the notch won't be a concern for your average person; and most people probably don't care about jimping.
As for the positive, the cost is unbeatable. You can buy these knives and keep them for a variety of purposes, from utility to self-defense (they conceal very easily and the pommel lanyard hole is big enough to lock the pinky into, providing instant indexing from the draw) to survival equipment/bug-out bags. Another thing about the cost is that if you decide the knife is not for you, you are only out of 30 bucks! People often ask why I have 10 or more different knives; other than enjoyment of using the appropriate tool for the appropriate task, and appreciating them as functional art, the truth is that you are extremely unlikely to find the "best" knife for a given task the first time you buy it. I'd rather buy three different $30-50 knives if I were on a budget, than buy one $100 knife that isn't the right fit for me.
The 1095 carbon steel is not over-hardened. I have seen it listed at 58 RC on the rockwell scale, but I am not sure if this is from the company literature or not; it sounds about right though and a 58 RC 1095 knife will take a lot of abuse and bend damn near in half before breaking. It won't hold an edge extremely long like a harder steel with a high carbon content, but it will be easier to sharpen and is tougher. It's a trade-off and you can get this thing extremely sharp very easily.
I actually used a paint remover on one of mine and ground jimping into it and modified the bevel into a convex edge. It is holding the edge really nicely, and has very aggressive, "toothy" properties. I sent the other two off to be professionally sharpened and modified to my specs by Richard E of bladeforums.com (see Tinkering, Maintenance and Embellishing section - he only charges $1 per inch of blade!). I will probably order a fourth to use as a "trainer" (I will totally dull and round off the edge and point, of course) in force-on-force scenarios and to practice my drawstroke without cutting my nice shirts.
This knife is very well thought out and despite my complaints has clearly been the product of collaboration between some great knife-makers and has undergone changes according to user feedback. This makes for the best sort of knife. Spyderco, another favorite knife brand of mine, practices "Constant Quality Improvement" or CQI.
